• Keep abreast of and, where appropriate, apply recent advances in machine learning and optimization, and their application to machine learning problems in RNA and LNP design.
• Design and analyze molecular and sequence libraries using statistical design of experiments, Bayesian optimization, active learning, and other data-driven approaches to maximize learning from experimental campaigns.
• Employ agentic software development tools to develop, deploy, and maintain ML-powered systems that leverage our internal assay data to accelerate our science.
• Utilize data science and software engineering best practices in day-to-day work, including automated testing, code review, and documentation designed to support reproducibility, collaboration, and effective use by AI agents.
• Collaborate with data scientists, data engineers, laboratory scientists, software developers, and engineers across Moderna.
• Communicate findings internally and externally.

• Ph.D.in Computer Science, Biological Engineering, Computational Biology, Biostatistics, Applied Mathematics, or related discipline with 0-2 years of professional experience, or a Master’s degree with 4+ years of relevant professional experience required.
• Demonstrated understanding of biotech research and engineering processes including one or more of molecular biology, discovery chemistry, microscopy, etc.
• Demonstrated prior experience in building sequence-function or QSAR models and applying them to molecular prioritization problems.
• Demonstrated ability to partner with experimental scientists to design, prioritize, and analyze molecular or sequence libraries that address biological or therapeutic questions.
• Strong foundation in statistics, including experimental design, regression/classification modeling, uncertainty quantification, hypothesis testing, and interpretation of noisy biological assay data.

• 2+ years of experience delivering data science projects.
• Outstanding communication skills (verbal and written).
• Success in communicating effectively to multiple levels of stakeholders.
• Demonstrated experience building research collaborations and executing complex and interdisciplinary research projects to completion.
• Fluency in Python, especially the scientific Python stack (Jupyter/Pandas/scikit-learn/PyTorch).
• Experience in identifying, procuring, and integrating external data sources as needed.
• Ability to manage multiple projects and effectively collaborate in a dynamic, cross-functional environment.
• Demonstrated experience and/or specialization in one of neural vision models, neural language models, diffusion models, or graph neural networks.
• Track record of publishing scientific research and/or method development.

At Moderna we are pioneering the development of a new class of drugs made of messenger RNA (mRNA). This novel drug platform builds on the discovery that modified mRNA can direct the body’s cellular machinery to produce nearly any protein of interest, from native proteins to antibodies and other entirely novel protein constructs that can have therapeutic activity inside and outside of cells. We have a clear mission to propel the field of mRNA science forward and deliver new medicines to patients and a unique vision for how to achieve this mission. Our Mission: To deliver on the promise of transformative messenger RNA (mRNA) science to bring new medicines to patients. Our Vision: To unlock the potential of mRNA by establishing an ecosystem of teams and partners that will work together to develop the broadest possible array of drugs, across diverse therapeutic areas and routes of administration, for serious diseases that are not treatable today.
